Sleep and Obesity in Teenagers: Impact of Sleep Length and Quality on Obesity and Diabetes Risks in Teenagers.

Further study details as provided by Hospices Civils de Lyon:

Primary Outcome Measures:

The influence of sleep extension on leptin level for the obese teens group. [ Time Frame: at the end of each sleep experimental period ] [ Designated as safety issue: No ]

Secondary Outcome Measures:

Difference between the two groups (obese vs non-obese) regarding sleep length and delta waves activity. [ Time Frame: during each sleep experimental period (habitual or extended) ] [ Designated as safety issue: No ]

Study the correlation between delta waves activity and habitual sleep length [ Time Frame: During each sleep experimental period ] [ Designated as safety issue: No ]

Study the correlation between delta waves activity and psychological, behavioural, anthropometric and physiological markers of obesity and its co morbidities [ Time Frame: During each sleep experimental period ] [ Designated as safety issue: No ]

On obese group, realisation of an extended sleep length period followed by an habitual sleep length period

Detailed Description:

Inclusion of 13 obese teens. Duration : 1 week of screening period + 1 week of intervention: habitual/extended sleep length + 1 week of intervention: extended/habitual sleep length. A wash out period of at least 3 months will be required between the two interventions.

Mild or severe sleep apnoea or excessive leg movements according to EEG analysis
